The web site for Calculus: Concepts and Contexts has been updated to refer to the Third Edition. The button Challenge Problems is now operational and provides additional challenging problems that are similar to those found in the Focus on Problem Solving sections in the textbook.

Note: Some of the links - such as "Algebra Review" and "Lies My Calculator and Computer Told Me" - point to Acrobat PDF files. For ease of navigation, these links open in a new browser window. If you can't open these links, please disable your popup blocker for this site.aaa
